a citizen of the United of America, and a resident of l assalc county oi Passaic, and

State of ew Jcrs have hivented certain new and useful improvements 11] Apparatus for Mixing Fluids, of which the following is specification. i Y My invention relates to the UBXIDQ: ol fluids in general,- and more specrlically comprises an improved apparatus for carbonatuig beer or charging other liquids with suitahle gasesl I l I 1 {2a in the process of brewing", the veer, aucr being fermented'and stored i'or, clariiicatlon, is subsequently treated with ltraeuscn in order to su )l the desired carbonic acid e'as.

Kraeusen 1s oun beer in the first stone of fermentation and is added. to the beer in storage where it slowly fermcnts and the gases of fermentation are absorbed into the beer, the process being carried on in a closed vessel under the pressure caused by the gene eration of the carbonic acid gas by the process of fermentation. This of course requires a second clarification of the beer and the 'whole process consumes from ten to twenty days time. I This process is shortened in the modern practice "by carhonsting' the beer by the direct injection into it of carbonic acid gas so that the-beer is ready for the market as soon as the first clarification. is su'llicientlycompleted for racking-the beer. My invention coin ,rises an improved apparatus for eil'ectlng 0.11s carhomzation. of the beer in a simple, uniform and entirely autoniatic manner. .i

. re test -cnn Oi apparatus (minor 3 mg my invention at present known to me is thus trated in the accompanying sheet of drawings, in which:

Figure l s a side elevation in partial section of the apparatus, and Fig. '2 is an enone form of valve used in the said apparatus .e I

Throughout the drzwvings, like reference figures indicate l'ike parts. i represents an ordinary beer pump or other source of liquid supply discharging into the pipe'2, which extends to the mixing chamher 3, connecting with the same through an inlet port at 4., 1

5 is a valve seat forming a second inlet port to the interior of said mixing chamber to "which is connected a pipe 6, con

erably by a check valve 7?,- and tion, iorces a stream oi iled pieiredancing valve 8, and extending to a reservoir ol car-- honic acid gas 9, or other source or supply of lluid under pressure.

Q conical valve mounted in the valve seat 5, and ii is a spreading nozzle for scattering the discharge through the valve seat 5 around the interior of the mixing chamber 3.

132 is a v alvc stein-extending from valve 10 to the piston 13, which preferably has a ries of lperlorations i l formed in it. This '1 'ston is preferably mounted in section 15 of the King chamber ol larger diameter than t e remaining portion and is interposed hot the inlet poi" rcvimisly referred-to and the outlet port ill, which connects with. the pipe 19, which forms the discharge outlet from the mixing chanihcr. This piston 13 may have short piston rep 1? con'nce ed to it which is adapted to telescope into the pocket" 18 formed in the head ol the mixing chamber and press aga nst the spring 2'? seat ed therein. The tension of this spring isadjustahle by turning; the adjusting screw 28.

21 is a second conical valve mounted in the valve-seat 20, which forms a supplemental inlet port or opening into the interior oi the mixing chamber through the perforated 4 charge nozzle 22. This valve 21 has a 2% which telescopes into the sleeve car" .on the lower side ol the valve 10 and has limited lost motion connection therewith by virtue of the pin and slot connection 26 shown in do nil in F 23 is a spiral spring: which imrinally ten to hold the valve 21 down onfits scat 2U 1 it is positively lilted therefrom by sullicic upward travel of the valve 10.

The operation of my invention is as lollows: The pump 3. being thrown into operahcer or other fluid into the mixing chamber 3. T he liuid passing through the perforations l-l oi the gist In 13 a certain pressure thereon This pressure, due to the llow of the liquid, is suificient to partly overcome the spring 2? and move the piston 13. The COIll1('lb;l-{)ll l2 then lifts the valve 10 a graduated distance and the valve-8 being properly set, a ilow of carhonic acid gas is discharged through the spreading nozzle 11 and mixes with the hecr v or othcr liquid. The greater the flow of lhe beer; the-more the Spill)" 2'? will be com-- pressed, theiurther the piston 18 will move the further valve 10 will he liilecl and the avlder the inlet opening allordcd to the honio acid d l'ien a further increased inv invention. ()ther forms of lo-w liquid from the pump 1 occurs, the vz'ilve 19 will lift for enough to lift the slotted sleeve so that the lower end of the slot Will strike the pin iii-the pin and slot connection This willopen the supplemental inlet port and cause an additional dischar e of gas through the perforated nozzle 22, This second discharge will be in a opposite to the direction of flow of the liquid and tend somewhat to retard said flow,

and also to produce a particularly effective admixture of geswith said liquid, such additional means for securing an eliective mixture being particularly necessary where the lieu of the beer is rapid. Of course when the ..eit ,r of flow of iluidifrom pump 1 decreases, 1 1e spring Z'Zwill expand and first permit the closure oi the valve 21 and then the conromeo gradual reduction of the discharge through valve seat '5, co responding to the o'l lieu of the beer. adveniiages ol my invention comprise its comp .ct and. simple form, the automatic regulation. of the discharge of gas according to the rate ol lieu of the beer and the intir J the mixture oi and beer prolorcing of the beer after clnug the numerous openings of the ,n 13 in itscll' tends to heighten oi the mixture ol" gas and beer. eviui'lnt, course, that various es could be made in the details of con mienv iiiustreted anddescribcd Without iting from the underlying principle of iston adapted to rctar-z. the .iio W of iinid and regulate the open of the valve might be substituted l or peiforuted p'ston shown. Other forum of valve could be used and the opening and clos ng of said valves might be regulated by .115 other than that of a piston interposed the main direction of flow of the liquid the mixing chamber. These and other liar changes 1 should consider merely tions of my invention.
